Sorry, I have 2 doubts about the EPR paradox. 1) Just check out if Im ok: What EPR proposed was that QM suggest that if two entagled particles, for example photons, prepaired in some special way, get away from each other then: a) if we measure their x-spin then one particle will get the value "a" and the other "-a" (a=+-1) b) if we measure their y-spin then one particle will get the value "a" and the other "-a" (a=+-1) c) if we measure their z-spin then one particle will get the value "a" and the other "-a" (a=+-1) This is weird because there seams to be an instantanous communication between the two particles which violates locallity (I know that the hidden variable hipothesys is not valid because of Bell inequalities and all that so the only possibility is the violation of locality) 2) Has anybody ever made any experiment with two EPR entangled particles and demostrated that the world effectively works this way? Because I see this instantanous communication ridiculous. Isnt it possible that this doesnt occur and that if we measure some property on both particles, this results are not this perfectly correlated???
